Over at TPM Cafe, Josh has had some cool threads with readers suggesting favorite books in a genre. I'm going to copy him. This week, finals end. When they end, I'm going on a week of vacation (but, if all goes well, you folks will have some sweet guest bloggers keeping you entertained) that, if I have my way, will be about as unpolitical as possible. With that in mind, what're your favorite nonpolitical nonfiction books? I'm talking quirky history books (though not epic, governments-and-wars history), sociology studies, biographies (nonpolitical ones, though), and so forth.
